本研究旨在以雷射為輔助能量作為植入銀膠與奈米碳管,應用於場發射顯示器。實驗中透過適當的光束能量調節與光罩選取,植入銀膠與奈米碳管時,可適度地控制碳管植入的範圍與圖樣,目前的實驗結果顯示將銀膠與奈米碳管植入一5x5陣列,單點直徑大小約 1.2 mm 發光區域為1cm2,發光測試時顯示植入區域幾乎都可點亮,啟動電場僅為 2.5 V/μm,當電場強度達到3.67 V/μm時,電流密度可達2.5mA/cm2,且在壽命測試上電流降為原來的63%、4.22 mA/cm2時,可長達50小時的穩定度。本技術的另一優點是可在常溫、大氣的環境下進行且不需任何後處理可達發光均均,具有相對低成本的優勢。
In this article, we present the technique of laser-induced forward transfer (LIFT) to deposit the carbon nanotube (CNT) and silver paste simultaneously on a variety of substrates for the purpose of field emission display at room temperature and in ambient environment. The Nd:YAG laser at the wavelength of 1064 nm was used as the light source. It was observed the types of transferred pattern were different as the laser fluence was switched from low, 0.4 J/cm2, to high, 1.96 J/cm2. Field emission measurements showed that a low turn-on field of 2.5 V/mm was obtained and the current density could reach 2.5 mA/cm2 as field voltage was at 3.67 V/mm. A lifetime test demonstrated that the field-emitted current dropped from its initial value of 6.55 mA/cm2 to 4.22 mA/cm2 during the first 12 hours and no significant degradation of 4.22 mA/cm2 more than 50 hours. In addition to its inherent straightforwardness and low cost in processing, the present method also shows the possibility of avoiding any post-treatment or activation processes that often used in the screen-printing method.
